Jeff,
Your list is very complete. Since I run a fine art print gallery myself (Rome, italy), i might have some suggestions:
-Cartridge disposal
-How to handle paper waste (printing from roll paper, what to to do with "rest paper", how to store?)
-Clean work environment (scanning, handling of prints --> using anti-static brushes). Cutting of prints.
-How to make a proper cut (for example with the rotatrim instruments (I still have it upside down, which seems to work better....)
-Efficiency: proofing images. When and where in the workflow and how big (for example I make a4 print of the whole image and an a4 crop (for sharpening and detail testing) when I print bigger then 40x60 cm
-File naming and notes about files. Labeling --> 1. originals 2. work 3. print
-Printing >1 customer in one job. Putting more customers in one job
-Handling of clogging and lines in prints (efficiency and action wise)
-Touching and cleaning cotton paper (taking away cotton seeds)
-Packaging and Shipping of prints
Just some daily issues I run into myself. the higher the pressure, the more difficult it is to be efficient and clean...)
